DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

The aromatic infrared bands (AIBs) seen throughout the interstellar medium (ISM) are generally thought to be carried by polycyclic aromatic hydrocarbons (PAHs) and their nitrogen analogues (PANHs).

Mass, time, space, and complexity — physicists in Leiden are launching eight new research projects tackling some of the most fundamental themes in quantum mechanics. Their goal: to push the limits of current quantum theories.

In September 2021, ACPA PhD Candidate Gabriel Paiuk will premiere a new work titled Sound Theory (The Clouds) as part of the 2021 Gaudeamus Muziekweek Festival. The performance will take place on September 10th, 20:30 at the De Helling (Utrecht, NL).

Leiden Professor of Number Theory Manjul Bhargava has been awarded a Fields Medal, widely regarded as the Nobel Prize for Maths. Bhargava is a professor in Princeton, and since 2010 has also been the holder of the Stieltjes chair in Leiden.

Conspiracy theories are of all times, and the government should never dismiss them as a fantasy of fools. Certainly not now, when it turned out that authorities made a conspiracy themselves with a journalist threatened with murder. Which proves that the truth is always more insane than you could have…

When professor Frank Israel graduated at Leiden Observatory some forty years ago, little did he know that one of his theories would be making headlines in 2018 - in the form of a 3D animation on the Internet, no less.

This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

‘I got into Nature last year, I was nominated for a faculty teaching award and my kids don’t care. But if your simulations get on The Big Bang Theory then that’s something!’ says Huib van Langevelde.

In this article, Jasmijn Boeken, explores in which ways the defining characteristics of the different zones can be found in the digital sphere.

Despite a lack of specific legislation on this issue, Dutch Minister of Justice and Security Dilan Yeşilgöz is allowing the national police force to experiment with facial recognition technology.

As of 1 June, Floske Spieksma has been appointed Professor at the Mathematical Institute in Leiden. Her field of study is Stochastic Decision-Making. Within this field, researchers develop mathematical techniques to analyse and improve processes within organisations. ‘As a professor, I hope to safeguard…

Measurements on a superconducting material show an abrupt transition between a normal metal and a 'strange' metal. The really strange thing, however, is that this abruptness disappears when the temperature falls. 'We don't have any theoretical machinery for this', says theoretical physicist Jan Zaanen,…

On Tuesday 15 September 2015, Bart de Smit has been appointed as professor of Algebra and Number Theory at the Mathematical Institute of Leiden University.

The goal of this book is to place architectural studies, in which people’s interactions with each other and material resources are key, at the crossing of both landscape studies and material culture studies, where it belongs.

What is the origin of educational ideas, e.g., the idea that intervention in infancy has long-lasting effects on development.

This dissertation provides a formal description of the relationship between diatopic/diachronic micro-variation and phonologization through analysis of the phonetic/phonological properties of unstressed vowel reduction and vowel insertion in two Northern Italian dialects.

Exploring the application of game-theoretic frameworks to quantum physics, this study creates novel AI training methods for the precise control of quantum systems.

Climate change is made up, the secret services murdered Pim Fortuyn and JFK, and the moon landing was a fake show. Conspiracy theories are of all times, providing sensation and entertainment, but also unrest and fear. The corona pandemic is new fuel for conspiracy theorists who set fire to 5G masts,…

This dissertation shows that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof.

This dissertation provides crucial but as yet missing empirical data on the tone accent opposition in the so-called

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

LCD screens use liquid crystals which have a high degree of order, even though they form a fluid. A new theory maps out the interplay between order, temperature and symmetry. Publication in Physical Review X.

What can Robotics and AI bring to archaeological theory and practice? In return, how can archaeology contribute to the developments in robotics and AI research? Colleagues tackled these questions at an event organised by the Faculty of Archaeology and sponsored by SAILS.

Ten years after its introduction, the controversial idea of Erik Verlinde on gravity is still a hotly debated topic, and is still surrounded by a cloud of scepticism. Scepticism in which the media have played a major role, theoretical physicst Koenraad Schalm says in an article by NWO. ‘The media simply…

The Court of Justice of the European Union is facing renewed scrutiny after expanding the reach of Article 2 TEU in Commission v Hungary. In a critical analysis published on Verfassungsblog, Martijn van den Brink argues that the judgment is indicative of the suffocating grip of “EU constitutional orthodoxy”…

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

There are a number of problems in philosophy that seem to share a similar possible solution: 'Why do promises and contracts bind?', 'Why ought citizens and judges obey the law?' and 'Can we realize the gains to be made from cooperation?'. All three problems (as well as some others) share a possible…

‘What I find most alluring about soil life is that you can steer it,’ researcher Martijn Bezemer of the Institute Biology Leiden (IBL) reveals. ‘You can ask: What do you want? And then I can transform the soil into something you need. At least, that is what we thought.’

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.
